Antifrogen N

Antifrogen® N is a liquid, tinted pale yellow, for use as a heat transfermedium in closed hot water heating systems, heat pumps and as coolingbrine in industrial refrigeration equipment. Antifrogen® N is not suitablefor the use in food or pharmaceutical applications.

Antifrogen L

Antifrogen® L contains as the base product the toxicologically harmless 1,2-propylene glycol, which is approved by the FDA (Food and Drug Administration, acc. § 184.1666 of the Federal Register from 1.4.1985), Propylene glycol is registered as a generally harmless food additive) in the USA.

Antifrogen® L is a blue tinted, clear liquid, which is used as a heat transfer medium in heat recovery systems and in the food and pharmaceutical sector or where the possibility of the heat transfer medium entering process water or hot water cannot be excluded.

Antifrogen Sol HT

Antifrogen® SOL HT is a physiologically harmless, yellowish, clear liquid based on an aqueous solution higher boiling glycols, which is used as a heat transfer medium in solar heating, especially those exposed to high thermal loads. The product is premixed with deionized water to give a frost resistance of about -23 °C.﻿

Antifrogen SOL Clean

Antifrogen® SOL Clean is a physiologically harmless, colorless, clear liquid based on glycol ethers with characteristic odor. Antifrogen® SOL Clean is used as a cleaning agent in solar systems.﻿

Antifrogen KF

Antifrogen® KF is a non-toxic clear liquid, based on an aqueous formate solution which is used as a low-temperature brine down to -50 °C in industrial and food refrigeration systems. The brine has a low viscosity at low temperatures.﻿

Protectogen C aqua

Protectogen® C aqua is a yellowish, water soluble, glycol free liquid which contains a highly efficient combination of corrosion inhibitors. The product is inhibited without the use of nitrite, amine, borate,phosphate and silicate.

Protectogen® C aqua is delivered undiluted and should always be dilutedwith water.

The concentration of Protectogen® C aqua in water should be 1.5 % v/v. That means that 1.5 l Protectogen® C aqua will be added into 98.5 l water. The water used to dilute Protectogen® C aqua shall contain no more than100 mg/kg (ppm) chloride.

Protectogen® C aqua is especially suitable for the use in cold water sets which do not require frost protection, i.e. in a temperature range from approx. +5 to +95 °C. This mixture does not offer any frost resistance and it is therefore not suitable for outdoor applications in winter. For protection from frostplease use our products Antifrogen® N, L, SOL HT or KF. By adding Protectogen® C aqua the specific heat transfer abilities ﻿of waterwill not be influenced significantly at all.﻿

With sustainability gaining paramount importance in the HVAC industry, these solutions contain a highly efficient combination of inhibitors providing corrosion prevention and long term stability. All these solutions are inhibited without the use of nitrite, amine, borate, phosphate and silicate, and do not contain CMR substances (Cancerogenic-Mutagenic-Reprotoxic).﻿
